Question

If f(x) = (√x-8) and g(x) =x+4, find the function h(x) such that h(x)= (f o g)^-1. Be sure to give a domain restriction if necessary.
Need to know how to get the answer as well because I have to show work. Really lost. Help?

Answer 1

I've written everything in the attached file.
hope it helps you.

Answer 2

Just wondering now, how do i find if there is a domain restriction on the inverse function?
